A rap sheet is a record of arrests and prosecutions. Arrest events occur when a person is arrested, or when they are fingerprinted and booked.
Each time a person is arrested and fingerprinted in Washington State, the police department sends a copy of the prints to the Washington State Patrol - WSP. All arrest fingerprints are also sent to the Federal Bureau of Investigation - FBI. The FBI maintains a record of arrests from across the country. The FBI may have outdated information in their database as they rely on local police and courts to update their information. As a result, the FBI data contains a notable amount of information with missing dispositions. Per FBI regulations, BCCU cannot distribute the FBI rap sheet to all facilities; for some facilities, it is up to the applicant to share the results with the facility.
